MentionShare: The AI Visibility Metric B2B Marketers Need

A new era of brand metrics

For years, B2B marketers obsessed over domain authority, keyword rankings, and organic traffic. These metrics made sense in the Google era. But as buyers shift to AI assistants, we need a new metric.

Enter MentionShare.

What is MentionShare?

MentionShare is the percentage of AI-generated answers that mention your brand, across a defined set of buyer-intent prompts.

For example: if you run 10 prompts across ChatGPT and Perplexity, and your brand appears in 3 of the responses, your MentionShare is 30%.

How to interpret your score

• ▸0–25%: Critical. AI is largely unaware of your brand. Immediate action needed.
• ▸25–50%: Developing. You're getting some mentions but competitors dominate.
• ▸50–75%: Strong. AI regularly recommends you. Focus on maintaining and expanding.
• ▸75–100%: Dominant. AI consistently recommends your brand first.

Why MentionShare matters more than domain authority

Domain authority measures how likely Google is to rank your page. But Google rankings are becoming less relevant as buyers use AI.

MentionShare measures something more important: how often AI recommends your brand to potential buyers at the moment of purchase intent.

A brand with a DA of 20 but a MentionShare of 60% will out-compete a brand with a DA of 80 and a MentionShare of 5% — because AI is becoming the primary research channel.

Tracking MentionShare over time

MentionShare isn't static. It responds to:

• ▸New content you publish (especially FAQ blocks and schema markup)
• ▸Reviews and citations on third-party sites
• ▸Competitor activity
• ▸AI model updates

Weekly tracking is essential. A drop in MentionShare can signal a competitor gaining ground or an AI model update affecting your citations.
